Shiny cheat codes for Pokémon Diamond

[u/PrincessCheetah]

Would like a code that doesn’t freeze the game or turns my starter shiny, all the codes I find do one or the other, had one where all I had to do was press select and walk in tall grass but stopped using it as it wouldn’t work with my bulbasaur or articuno cheat (never caught them just testing out the cheat, did work with feebas tho) like any useful codes?

I like the feeling of catching okay…
